The BA1-B0-11-485-1B1-MT is a single-pole circuit breaker manufactured by Littelfuse Inc., designed for reliable overcurrent protection in electrical systems. Rated for 8.5 amperes at a maximum voltage of 277 volts, this component provides precise circuit interruption when fault conditions occur. The breaker utilizes a magnetic hydraulic delay trip mechanism, which ensures accurate tripping characteristics while avoiding nuisance trips caused by temporary inrush currents.
Equipped with a manual lever actuator, this device allows for straightforward manual operation and status indication. It is configured for panel mounting, making it suitable for integration into control panels, industrial equipment, and commercial electrical distribution boards. The absence of illumination simplifies the design for applications where indicator lights are not required.
Engineers specifying this breaker should note its robust construction tailored for standard AC line frequencies. The magnetic hydraulic delay feature makes it appropriate for protecting circuits with moderate startup loads. Its single-pole configuration offers targeted protection for individual branches within a larger system. Procurement teams can reference distributor part number 432-BA1-B0-11-485-1B1-MT-ND for sourcing.
